Okay, PS Jedi Power Battles is an older game. I've beat it every which way in 1 Player.

For the first time, I am playing it in 2-player mode...how do you unlock the Survival Challenge level?

In 1 player, you beat it with Mace and it unlocks it. We beat 2 player with Mace and Qui-Gon, but it remains unlocked.

Can anybody throw me a bone here?

I don't believe that it can even be accessed in the two player mode.. but I'm not sure about that nor am I sure if you're referring to the DC or PSX version of this game.

I don0t know it , too. sorry man....:(
